L3 switch loses connectivity to its own SVIs?

I've seen an issue where on a Cisco 800 series L3 switch/router where the MAC address for the SVIs disappears from the device and the IPs drop from the routing table.

Even a reboot doesn't seem to fix this - only removing all routing config, removing the SVIs and reapplying everything fixes it. Has anyone seen this before?
